Robertshaw Controls 5001-B2-A Level Lance Transmitter

Robertshaw Controls 5001-B2-A Level Lance Transmitter is a pulse‑frequency modulation (PFM) transmitter that forms the sending element of Robertshaw's Level‑Lance level‑measurement system. It is designed to operate with Level‑Lance receivers and is compatible with models 5001, 5100, and M5008, enabling integration into existing Level‑Lance installations. The unit is powered by 15 VDC supplied by the Level‑Lance network and outputs a PFM signal that encodes level information for the corresponding controller. As part of the Level‑Lance family, this transmitter supports capacitance‑based level sensing used in industrial tanks and vessels, providing the signal interface between the probe assembly and the Level‑Lance receiver to monitor liquid levels with compatible control equipment.
